You need to save all lake data on a 32 Gigabyte SD/micro-SD card formatted to FAT32. For Mac users, the format type is: MS-DOS (FAT).
Larger cards are not compatible. Smaller cards will limit how much chart content you can save to the card for future purchases.
Notice! As of October 3, 2022, new single lake and layer purchases from ChartSelect are no longer available. Our new format allows only the purchase of LakeMaster Legacy regional maps, which are only available via download.
Any previous purchases will still be supported and function like normal. However, no new layers can be purchased, and there will be no future updates to existing layers.
